78 Configuration Parameters
Relay Parameters The Relay parameters control the operation of the on-board relay, as well as
the relays on the Expansion Relay (XM-441) module. Use these parameters to
configure which alarm(s) the relay is associated with, as well as the behavior of
the relay.
Speed Range Low The lesser threshold of the machine speed range.
This value must be less than the Speed Range
High value.
This parameter is not used when Speed Range
Enabled is disabled.
RPM
Speed Range High The greater threshold of the machine speed range.
This value must be greater than the Speed Range
Low value.
This parameter is not used when Speed Range
Enabled is disabled.

IMPORTANT
A relay can be defined, regardless of whether or not it is
physically present. A non-physical relay is a virtual relay.
When a relay (physical or virtual) activates, the module
sends a Change of State (COS) message to its master,
which acts on the condition as necessary. An XM-440
Master Relay Module can activate its own relays in response
to a relay (physical or virtual) activation at any of its slaves.

Parameter Name Description Options/Comments
Number (XM Serial Configuration
Utility only) Sets the relay to be configured in the XM Serial
Configuration Utility. Relay Number 1 is the on-board relay.
Numbers 2 through 5 are either relays
on the Expansion Relay module when
it’s connected to the module or virtual
relays.
Virtual relays are non-physical relays.
Use them when you want the effect of
the relay (monitor alarms, delay, and
change status) but do not need an
actual contact closure. For example, a
PLC or controller monitoring the relay
status.
Note: The Relay Installed parameter
indicates whether a relay is a virtual
relay or a physical relay on a module.
